As easy as it sounds to retread your tire, when it comes down to it, there are quite a number of steps that need to be carried out.
Tires aren't just inspected manually. They go through a test called Laser Digital Shearography in which the laser scans through the whole tire and the mechanic will identify all the damages at the intricate portions. This will give the mechanic a better idea of whether he can perform retreading or not.
Once the initial inspection is done, we can move on to Tire buffing. This process involves taking out or cutting out certain portions of the tires to remove unnecessary elements and improve the flexibility of the tread.
Most importantly, by doing this, you can easily remove the blocks of tread formed on the tires which cover the area between the rubber and the grooves of the treads. This process is performed by computerized machines that are operated by skilled mechanics. We really suggest you consider an authorized dealer or service center when seeking to retread.
This stage of the process involves finding out the cause of the damages to the tires and also treating these damages in a way to avoid any further damage in the future. Even minute errors are made sure to not be left unsolved. For instance, small holes in the tires are identified by passing high voltage electricity through the tire. This also gives the tire the ability to regain its strength.
After completing the whole process mentioned above, materials are added to the casing through the aid of the computerized machines to improve the natural properties of the tire.
Computers are employed in this process, mainly to avoid any type of error caused to the systems and to improve the efficiency of the tire. Computers have become pretty accurate these days, and are slowly replacing manual jobs like these every single day.
This next step involves taking the tire and subjecting it to heat, before checking the level of the tire. This is done to find out the quality of the rubber and to verify whether it is still vulnerable or not.
This is the final step where we can find out if the tire is prepared to hit the road or not. Here, a series of inspections are done to make sure that the tire has no sort of imperfections on itself and if any of them are spotted they can be replaced immediately.
The tire goes through two tests namely visual and tactile inspection and inflation test. After all the tests are done they are then sent to the first test of Shearography where if there are any minute errors still left, they may be identified.
